Sugar as a coagulant for crepe rubber, O. de Vries (ArcJi. Ruhbcrcult. 

 Nederland, Indie, 1 {1911), No. 1, pp. 5-16). — As a result of experiments con- 

 ducted in part by the author and in part by N. L. Swart and A. J. Ult6e the 

 conclusion is reached that the difference between rubber coagulated by acetic 

 acid and by sugar is insignificant. Such difficulties as arise in the practice of 

 sugar coagulation can be overcome, and it is believed that sugar might possibly 

 be the coagulant most fitted to replace acetic acid if necessary.
